Controlled demolitions take a lot of time to set up and the inside of the building is basically destroyed beforehand. I can't figure out why that is so hard for these people to understand.

Roxdog, what are your comments on the proof that was provided about the amount of work that needs to be done to a building prior to detonating it?
We weren't talking about the 19 hijackers, so don't try changing the subject again. We are waiting for your comment on the proof that was provided.
Edit: Roxdog, it doesn't take smelting temps to weaken the steel.

Thanks for that letter Roxdog, at least it is something else. However, how and when was the building rigged with explosives? Have you seen what needs to be done to a building before it is brought down by controlled explosions? The building is literally gutted out and wires are all over the place for the rigged explosives. When would this have been done? Te building would not come down with a couple of sticks of dynamite thrown into basement.
This is a picture from earlier in the thread.
In order to bring a building down, it must be rigged like this. When was all this done?
Here is some more on the amount of work need to be done before the building is brought down:
While it only takes about four seconds to detonate all of the charges to drop a building, it usually takes months of work to prepare the blast.
It doesn't take a lot of explosives to blow out a pillar or wall section. There are, however, hundreds of these small shots involved in a single elevator blast. Our largest shot involved two elevators, the "D" . house and the "D" west annex. In less than eight seconds, both elevators were destroyed with a total of roughly 800 separate small shots.
Taken from here
This was a smaller building that WTC 7 and it took 800 of these charges to be in place by drilling holes in the concrete. Again, when was this done?

Yeah, I saw that. How is that proof? All it does is ask more questions and answer none.
You can permanently distort the beams with a temperature difference of only about 300°F.
If there was one part of the building in which a beam had a temperature difference of 300°F, then that beam would have become permanently distorted at relatively low temperatures. So instead of being nice and straight, it had a gentle curve. If you press down on a soda straw, you know that if it's perfectly straight, it will support a lot more load than if you start to put a little sideways bend in it. That's what happened in terms of the beams. They were weakened because they were bent by the fire.
But the steel still had plenty of strength, until it reached temperatures of 1,100°F to 1,300°F. In this range, the steel started losing a lot of strength, and the bending became greater. Eventually the steel lost 80 percent of its strength, because of this fire that consumed the whole floor.
If it had only occurred in one little corner, such as a trashcan caught on fire, you might have had to repair that corner, but the whole building wouldn't have come crashing down. The problem was, it was such a widely distributed fire, and then you got this domino effect. Once you started to get angle clips to fail in one area, it put extra load on other angle clips, and then it unzipped around the building on that floor in a matter of seconds.
